Relocate the permission evaluator (wildcard matcher + rule evaluation) to the
shared kernel and flip 43 non-frozen importers. A re-export shim remains at
new_chat/permissions.py for the frozen single-agent stack (chat_deepagent and
subagents/{config,providers/linear,providers/slack}); it will be removed when
that stack is retired.
Promote the agent feature-flag resolver (AgentFeatureFlags / get_flags) out of
`new_chat` into the cross-agent `app/agents/shared` kernel.
feature_flags is a pure leaf consumed across the multi-agent middleware stack,
the chat routes, and tests. Moved it via git mv (content unchanged) and flipped
all 37 importers to app.agents.shared.feature_flags. A thin re-export shim
remains at new_chat/feature_flags.py only for the not-yet-retired single-agent
(chat_deepagent); it goes away with the single-agent deletion.
Behavior-preserving: only import paths change. 1243 tests green.
Only MCP tools have a persistence target for 'approve_always' (the
connector's trusted-tools list); for native tools the decision lives
only in the in-memory runtime ruleset. Reflect that in the wire palette
so the FE can stay a pure renderer of allowed_decisions instead of
peeking at context.mcp_connector_id to decide whether to show the
'Always Allow' button.
The backend still accepts an 'approve_always' reply for any tool kind
(in-memory promotion is harmless), it just doesn't advertise it when
there's nowhere to persist.
Renames the SurfSense HITL extension decision-type from "always" to
"approve_always" so it sits in the same verb-first family as "approve",
"reject", and "edit". The Python constant is now SURFSENSE_DECISION_APPROVE_ALWAYS;
the wire value, the permission-domain decision_type, and the FE union members
all match (no wire/internal mismatch).
Both the multi_agent_chat permission middleware and the legacy new_chat one
accept the new wire value; the FE types.ts union is updated accordingly.
The "context.always" payload key is intentionally left untouched - it's the
patterns-to-promote field, semantically distinct from the decision type.
Until now an "Always Allow" reply only updated the in-memory runtime
ruleset, evaporating after the session ended. Persist it to the
existing connector.config['trusted_tools'] list so the next session's
fetch_user_allowlist_rulesets picks it up and the user is never asked
again for the same (connector, tool) pair.
- TrustedToolSaver + make_trusted_tool_saver(user_id) in
user_tool_allowlist: opens its own session via async_session_maker
per call, logs and swallows failures (in-memory promotion is the
canonical "always" path, durable persistence is opportunistic).
- PermissionMiddleware._process is now pure: returns
(state_update, list[_AlwaysPromotion]). aafter_model awaits the
saver for each promotion; after_model discards them. Promotions are
only emitted for tools whose metadata exposes mcp_connector_id, so
native tools and KB FS ops are correctly skipped.
- main_agent factory builds the saver once per turn and stashes it in
dependencies["trusted_tool_saver"]; pack_subagent and the KB
middleware stack forward it through build_permission_mw.
- Renamed pm._process(state, None) call sites in two existing tests to
pm.after_model(state, None) so they exercise the public hook
contract instead of the now-tuple-returning private method.
The FE permission card needs mcp_connector_id, mcp_server, and
tool_description in the interrupt context to render "Always Allow"
against the right connected account. Thread the tool through the
ask pipeline:
- pack_subagent → build_permission_mw(tools=...) → PermissionMiddleware
(tools_by_name) → request_permission_decision(tool=...) →
build_permission_ask_payload(tool=...) projects card fields out of
BaseTool.
- mcp_tool.py: stdio path now stashes mcp_connector_id in metadata for
parity with the HTTP path.
